| True or False-Many of the nonmetals are gases at room temperature | True |
| What are two things that are true about physical properties in non metals? | Solid nonmetals are brittleThey usually have lower densities than metals |
Would a metal in Group 13 be more less or just as reactive as a metal from group 1?
A metal in group 13 is less reactive than an metal in group 1 because the farther right on the periodic table, the less reactive.
What are the elements in group 3/12 called?
Groups 3-12: Transition Metals Transition metals have more valence electrons and are less reactive than metals in the first two metal groups. The transition metals are shiny. Many are silver colored. They tend to be very hard, with high melting and boiling points.
Is the following sentence true or false the subatomic particles that play the key role in determining the properties of an element are electrons?
The subatomic particles that play the key role in determining the properties of an element are electrons. True. They display a wide range of physical and Chemical properties. Some are metals, nonmetals, and metalloids.
Do group 13 elements gain or lose electrons?
Except for the lightest element (boron), the group 13 elements are all relatively electropositive; that is, they tend to lose electrons in chemical reactions rather than gain them.
What is true of all elements in a group?
The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.
What are the elements in group 12 called?
zinc group element, any of the four chemical elements that constitute Group 12 (IIb) of the periodic table—namely, zinc (Zn), cadmium (Cd), mercury (Hg), and copernicium (Cn).
